Application -led August 10, 1921.

To all whom 'it 'may concern:

Be it known that I, JOHN LALLY, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, haveinvented certain new and useful Improvements in Building Columns, of which the following is a specification.

My invention relates to buildingcolumns of the re-inforced concrete type and it is my object to produce a built-up column in which the pieces will be solidly united without the use of rivets, tie rods or pins, which will be simple and cheap to construct and in which the crown or capwill occupy as little space as possible. v

In the drawing Fig. l is a view, partly in section, of one form of my improved column; Fig. 2 a top view of the structure of` Fig. l; Fig. 3 a view, partly-in section, of a column having the brackets in two pieces; Fig. 4 a view, partly in section, of a column 'provided with hook on brackets; and

Fig. 5 a view of the slotted pipe used in the construction of the `.bracket of Fig. 4.

In the form shown in Figs. 1 and 2 the column comprises a casing slotted at its upper end. A bracket 2, extending beyond the pipe on either side, is provided with integral lugs 3 3 projecting from its upper edge and a central cut-out portion 4. The top plate 5 has apertures 6-6 adapted to engage the lugs 3-3 and a central aperture 7 adapted to register with the cut-out portion 4 of the bracket. ,y Holes 8, 8, 8, 8 are formed in the top plate for attaching the floor beams.

In making up brackets embodying my inventin the bracket is placed in the slots in the casing and the top plate laid on with the holes 6-6 engaging the lugs on the bracket which are then upset to unite the bracket and top plate. The bracket and casing slots may be welded together to unite the cap and casing and to prevent spreading ofthe slots under load;

A plug is then placed in the central aperture of the top plate and extends into the .cut out portion of the bracket. The column is then inverted and lilled with plastic maf terial such as concrete. After the concrete has set the plug is removed leaving the central hole to receive the pintle of a' superimposed column which passes through the aperture 7 and into the space left by the cut-out in the top edge of the bracket.

As shown in Fig. 3 the casing 1 is slotted Serial No. 491,179.

as in making the column of Figs. l and 2 but the bracket instead of being in one piece extending clear across is made in two pieces 2', 2 which are preferably welded to the slots and have the lugs 3--3 thereon to engage t-he apertures in the top plate exactly as they do in the columns ofFigs. l and 2.

In the form shown in Figs. 4 and 5 thevl casing l is slotted below the top edge as best shown in Fig. 5 and the brackets 8 are formed with notches 9-9- in their upper edges, cut ofi' at their lower inner corners 10-10 and provided with the lugs 3-3 which engage the apertured top plate as is the case in the columns hereinbefore described. In assembling, the brackets are hooked into. the slots with their upper edges flush with the top of the casing and the notches 9 receiving the'casing wall, the cut ofi corners permitting entrance. The brackets may be welded to the edges of the slots if desired.

rlhe central aperture intended to receive the pintle of a superimposed column may be omitted if desired in any or all of the columns shown and described.

It is apparent that the integral lugs for uniting the brackets and top plate and the apertured top plate are common to all the forms of columns shown herein.

By this construction I eliminate the rivets, tie-rods, bolts and screws heretofore used in making built-up columns and utilize a few.`

simple pieces which may be of rolled sheet metal and a piece of tubing or pipe in.producing a column having strength and light-V lness.

I claim 1. A building column comprising a slotted casing, a bracket in said casing slot provided with a cut out portion, a lug on said bracket and an apertured top plate, one aperture of which engages the bracket lugand the other of which alines with the cut out portion of the bracket, the bracket and slot edges being Welded together. l

2. A building column comprising a casing provided with opposed slots, a bracket in said slots provided with a cut-out central portion, lugs on said bracket and a top plate provided with apertures engaging the bracket lugs and a ,centralaperture alining with the cut-out portion of the bracket, the bracket and slot edges being welded together.

3. A building column comprising a casing slotted below the top edge, a bracket in said slot, e notch in said bracket engaging the top of the slot and an integral lug eX- tending above the bracket, the topline of the bracket being flush with the top end of 5 the casing, en epertured top pla-te the aperture of Whicli engages the bracket lugs.

fl. A. building column comprising a casing slotted below its top edge, a bracket in said slot, said bracket being notched with the l@ notch engaging the top end of the slot and an integral lug extending above thebracket, the top line of the bracket being flush with the top end of the casing, an apertured top plate, the aperture of which engages tbe A bracket lug and a illing of plastic material 15 within said casing.,

In testimony whereof I have axed my signature.

JHN LALLY.
